Typical Specifications
Non-spring return damper actuators shall be the
direct-coupled type that requires no connecting
linkages. The non-spring return actuators shall have
a self-centering damper shaft coupling that assures
concentric alignment of the actuator’s output
coupling with the damper shaft and be capable of
direct mounting to a shaft up to a 1-inch (25 mm)
diameter. Actuators shall provide stall protection
throughout the full range of rotation. All non-spring
return actuators shall be capable of both clockwise
and counterclockwise operation. All actuators shall
hold position in the event of a power failure. All
actuators shall return to the 0 position in the event
that only the control signal is lost. All actuators shall
provide a means of manually positioning the output
coupling in the absence of power. Dual
independently adjustable auxiliary switches must be
integral to the actuator. All actuators must be
precabled and provide an easily readable high
contrast yellow on black position indicator. All
actuators shall be UL873, CE and CSA22.2 listed
and manufactured under ISO 9002 and ISO 14000
procedures. Actuators shall be designed for a
minimum of 60,000 full stroke cycles at the actuators
